(3)The Commission Action Plan for Financial Services identifies a series of actions which are needed to complete the Single Market in Financial Services, and announces the development of supplementary prudential legislation for financial conglomerates which will address loopholes in the present sectoral legislation and additional prudential risks to ensure sound supervisory arrangements with regard to financial groups with cross-sectoral financial activities. Such an ambitious objective can only be attained in stages. The establishment of the supplementary supervision of credit institutions, insurance undertakings and investment firms in a financial conglomerate is one such stage.
